There’s a brouhaha occurring on the internet tonight as it has emerged that if you had linked your Epic Games account to your PlayStation 4 to play Fortnite you cannot use the same account to play the game on Switch. If you had played on mobile, PC, or Xbox One the account is not locked and works fine.
According the message displayed this is not the fault of Epic, and even worse if you unlink your account from your PlayStation 4 it still remains locked and unable on used on Switch.
There’s a lot of angry people demanding this be fixed and it does appear to be a problem created by Sony. They have yet to respond to the situation.
